## Modelling of the Performance of AG/SAG Mills

Transport of slurry through the mill is described by a function which relates the holdup of slurry, grate design, grate open area and mill speed to the volumetric discharge rate through the grate (Morrell and Stephenson, 1996): Jp = k Q05 g125 A05 f067 D025 (7) where Jp = fractional slurry holdup D = mill diameter (m)SAG mill throughput as a function of grate open area As shown in Figure 2 the grate open area has a strong effect on Sossego SAG mill throughput The nominal capacity of the circuit should be achieved with a combination of 135% ball charge and 108% open area with 3 and 35 inch apertures The mill is currently operating with 525 and 55 inch steel balls Other issues addressed under the(PDF) Optimisation of the Sossego SAG mill | MauricioSingle STAGE SAGAG MILLING DESIGN Orway Mineral is possible, if the pulp thickness up suddenly, to block the grates at the discharge end Discharge grate design The pebble mills use the grate discharge system asGet Price; Pebble Mill Application and Design Paul O Abbe Discharge grate The discharge grate is designed to retainpebble mill grate
